SELECT FROM <model>.DIMENSION_CONTENT (DMX)

 

Updated: March 2, 2016

A mining model can be used as a dimension in an OLAP cube, where each node in the model is represented as a member of the dimension. The SELECT FROM <model>.Dimension_CONTENT statement returns the content of the model that pertains to its usage as a dimension.

  
SELECT [FLATTENED] [TOP <n>] <expression list> FROM <model>.Dimension_CONTENT   
[WHERE <condition expression>]  
[ORDER BY <expression> [DESC|ASC]]  

n
Optional. An integer that specifies how many rows to return.

expression list
A comma-separated list of related column identifiers derived from the content schema rowset.

model
A model identifier.

condition expression
Optional. A condition to restrict the values that are returned from the column list.

expression
Optional. An expression that returns a scalar value.

Algorithm providers define which content is returned, and how to organize it. For example, the provider might limit the number of nodes that are described in the dimension content.

The following table lists the columns that can be queried for the dimension content, and the function that each column performs as a data mining dimension.

CONTENT rowset columnFunction in data mining dimension
ATTRIBUTE_NAMEMember property.
NODE_NAMEMember property.
NODE_UNIQUE_NAMEKey attribute.
NODE_TYPEMember property.
NODE_CAPTIONCaptionColumn for Key attribute.
CHILDREN_CARDINALITYMember property.
PARENT_UNIQUE_NAMERelatedAttribute for Key attribute (ParentAttribute in parent-child hierarchy).
NODE_DESCRIPTIONMember property.
NODE_RULEMember property.
MARGINAL_RULEMember property.
NODE_PROBABILITYMember property.
MARGINAL_PROBABILITYMember property.
NODE_SUPPORTMember property.
